Similar results are obtained by a calculation using two covalence parameters and other known free-ion parameters. In this method, the calculated values of Nx ≌ 0.92 and N6≌ 0.89 are obtained. The parameters in the generalized effective Spin-Hamiltonian are calculated. It is found that the g-factor in the modified term results from the contribution of the fourth order perturbation, and its order of magnitude is about 10-5. The effective Hamiltonian which is used to describe the R line of ruby was obtained.

    Solubility data of KClO4 in mixed solvents, namely, methanol-benzene, methanol-toluene, methanol-Carbontetrachloride and methanol-cyclohexane, are reported in this paper, The "free ion" concentrations of KC1O4 and KNO3 are calculated by using the association constants given by A,D'Aprano and C. W. Davies[2] of these salts in methanol, The medium activity coefficients fMX expressed in terms of S0/Smand (S0)±/(Sm)± are approximately equal and related to rnol fraction XNc of nonelectrolytes in the mixed solvents by the following empirical formula: lg/MX = kXNe where So and Sm are solubilities of salts in methanol and mixed solvensts respectively; the Subscript ± is used for the "free ion" and k is a constant. The formula for the Solvation number of electrolyte n+ +n-=-2lgfMX/lgφP is not valid for KClO4 in these Mixed solvents, where n+ +n- is the sum of the solvation number of positive and negative ion; φp is the volume fraction of methanol in mixed solvents, This result indicates that the solvation layer of ClO4 is not entirely formed by the methanol molecules and the nonelectrolyte exerts some effects on the solvation layer too.experimental data of KNO3, formulas of the solubility and of Solvation numbers are quoted from the former paper of li, Huang and liu[1].

    本文测定了KClO_4在甲醇-苯,甲醇-甲苯,甲醇-四氯化碳及甲醇-环己烷四个混合溶剂中的溶解度。使用A.D'Aprano[4]和C.W.Davies[2],报告的KClO_4及KNO_3在甲醇中的缔合常数,计算得“自由离子”浓度。盐的介质效应活度系数f_(MX)以S_o/Sm或S_(o+)、D_(m±)的表示值趋近相等,与非电解质的摩尔分数X_(Ne的关系符合经验公式:1gf_(MX)=kX_(Ne),这里S+o和S_m分别是盐在甲醇和混合溶剂中的溶解度;脚注(±)标识“自由离子”;k为常数。电解质的溶剂化数公式:n_++n_-=-21gf_(MX)/1gφ_ρ,对KClO_4在这些混合溶剂中的情况并不适用,这里n_++n_-是正、负离子溶剂化数之和;φ_p是甲醇在混合溶剂中的体积分数。这个结果表明ClO_4~-的溶剂化层不是完全由甲醇分子所形成,非电解质也影响着ClO_4~-在这些溶剂中的溶剂化层。 KNO_3的实验数据,溶解度公式和溶剂化数公式是引自李芝芬、黄子卿、刘瑞麟以前的论文。

    An analytic approximation wave function of free ion N_i~(2+) is obtained from Watson's SCF—3d orbit crystal field energy levels are then calculated with this wave function using the point charge dipole model in the NiNb_2O_4. The calculation is based on real C_2 symmetry of the crystals arising from the descent of symmtry in two steps: O_h→C_(2u) and C_(2u)→C_2. Sometimes it is difficut to determine numerous parameters from spectral data in treatment of low symmetry crystal. We try to covecome this difficulty....
